What is Optimization and Performance of an Optical Cardio-magnetometer about?

Cardiomagnetometry is a growing field of noninvasive medical diagnostics that has triggered a need for affordable high-sensitivity magnetometers. Optical pumping magnetometers are promising candidates satisfying that need since it was demonstrated that they can map the heart magnetic field. For the optimization of such devices theoretical limits on the performance as well as an experimental approach is presented. The promising result is a intrinsic magnetometric sensitivity of 63 fT / Hz^1/2 a measurement bandwidth of 140 Hz and a spatial resolution of 28 mm.
